Effects of postresponse visual stimuli on visual discrimination learning in the rhesus monkey

To learn more about the mechanism (or mechanisms) involved with postresponse stimulus processing during discrimination learning, a series of studies was conducted with monkeys to determine why the combined relevant and irrelevant stimuli impair learning more than irrelevant stimuli appearing alone. It was found that: (a) the greater size and complexity of the combination of stimuli were not responsible for the greater deficit, while the presence of the relevant stimuli (S^D and S^Δ) within the stimulus combination apparently was; (b) the more similar the postresponse irrelevant stimuli were to the relevant stimuli the greater the deficit that resulted; and (c) monkeys that had earlier learned to discriminate the relevant and irrelevant features of a combination showed no learning impairment when this same stimulus combination was later presented after the response during a new learning problem. These results were interpreted as evidence that: (1) processes associated with learning a discrimination problem do not end with the execution of a choice response; (2) postresponse stimuli produce greater impairment in discrimination learning when they are distorted versions of the relevant stimuli; and (3) the impairment resulting from postresponse irrelevant stimuli occurs primarily when this misinformation is processed and misperceived as being relevant to learning the discrimination problem.     

Stimulus control of free-operant avoidance: The contribution of response rate and incentive relations between multiple-schedule components

The associations formed in the components of a multiple schedule can be classified as (1) stimulus-response (S-R) associations and (2) stimulus-reinforcer (S-S^R) associations. The present experiments sought to determine the individual contribution of these S-R and S-S^R associations to stimulus control by manipulating them independently. Responses postponed shocks by 25 sec in the presence of a tone alone and a light alone in all experiments. The contingencies programmed in the absence of both tone and light established a reference for the S-R and S-S^R associations in tone and in light. All four possible combinations of signalling response increase or decrease together with incentive increase or decrease were studied. Although the influence of the contingencies operating in the absence of tone and light was difficult to detect from response rates in tone or light, presenting tone and light together revealed clear effects. Response rates in tone and light together relative to those in either alone depended upon the contingency operating in the absence of tone and light. Stimulus-response and stimulus-reinforcer associations appeared to counteract each other when in opposition and combine together to enhance each other when in agreement. This suggested that the associations of a stimulus to response and to incentive combine algebraically in determining stimulus control. An algebraic analysis in terms of the S-R and S-S^R associations conditioned to the stimulus elements comprising the training and test stimuli accounted for the observed patterns of data.     

Effects of expectancies of different reward magnitudes in transfer from noncontingent pairings to instrumental performance

In two experiments, rats received noncontingent pairings of two stimuli with food reward, one paired with small reward and the other with large reward, and received bar press training with large reward or with small reward. When the noncontingent stimuli (NS) were presented for test during subsequent rewarded bar pressing and during early extinction of bar pressing, responding for each group was faster in the presence of the NS which was paired with the same reward magnitude that group received in bar press training than to the NS which had been paired with a different reward magnitude. As extinction progressed, all groups responded more slowly in the presence of the NS which had been paired with the large reward than in the presence of the NS which had been paired with small reward. These results were interpreted as indicating that responding in the presence of an NS depends on: (i) whether the reward expectancy elicited by the NS has been conditioned to the instrumental response, and (ii) the relationship between the reward expected in the presence of the NS and that received in test.     

Agreeableness and the common core of dark traits are functionally different constructs

The Dark Factor of Personality (D) has been suggested as the basic disposition underlying dark traits, thereby representing their common core. However, it has also been argued that such commonalities reflect the low pole of Agreeableness. The present study (N = 729) employed five established inventories to model the Agreeableness construct and considered seven theoretically derived criterion variables, including one behavioral outcome. Results indicate that Agreeableness and D exhibit a substantial, but far from perfect, association of r = −.64. Further, D incrementally improved the prediction of all but one criterion measure. These results speak against the notion that the commonalities of dark traits can be reduced to low Agreeableness and rather support the contention to consider Agreeableness and D as functionally distinct constructs.

Between Wonder and Doubt: Psychoanalysis in the Goal-Free Zone

This paper examines the experiential dimensions of wonder and doubt as one way to articulate the creative and growth-promoting tensions between the medical/scientific model and the spiritual/mystical model. Both forms of experience, it is argued, function as necessary elements in a psychotherapy that integrates psychoanalysis and spiritual praxes. Fundamental differences between the medical/scientific model and the spiritual/mystical models are examined. The notion of the gap serves to illustrate these diametrically opposed, albeit compatible and necessary, points of view. The multifaceted layers of movement between Buddhism and psychoanalysis typify interacting dynamics between the two disciplines and provide a focal point for discussion. The paper then explores parallels between the Zen Buddhist notion of Satori as explicated in the writings of D. T. Suzuki and Wilfred Bion's notion of O. Theoretical aspects of the discussion provide a backdrop for exploring clinical experience regarding the relationship between acceptance and change, the clinical relevance of the Buddhist notions of gaining idea and basic goodness. The author also explores relationships between presence as actuality and ideal; knowing and not knowing; wonder and doubt. Clinical material supports the theoretical aspects of the discussion.     

The history of Russian psychoanalysis and the problem of its periodisation

The formation and spread of the psychoanalytic teaching of Sigmund Freud and his followers is one of the most significant events in the life of the spirit in the twentieth century. The recognition of this as an historical fact--irrespective of its relation to Freud and his ideas--assumes of course and need to gain a proper understanding and appropriate interpretation of psychoanalysis in all its dimensions. Generally speaking, the history of psychoanalysis and the psychoanalytic movement has been researched quite fully, although for a variety of reasons and circumstances there are a number of gaps in it. Perhaps the most important of these is the history of Russian psychoanalysis, which has developed within a country where, at the beginning of the century, Freud's works were translated and published in a most effective and representative way, and where psychoanalytic ideas drew a response both from specialists and among the public at large, although in content and inclination the Russian mentality did not at heart suit a psychoanalytical treatment of man and his culture.     

The Ability of Face Viewpoint Transformation Remains Immature at Age of 12: Evidence from Recognition of Faces with Different Familiarity in Children

Children are immature in face recognition, particularly in face configural decoding. This study examines the developmental difference of face recognition in another mechanism: viewpoint transformation processing. Adults and sixth‐grade children were instructed to match a series of one‐tone black face silhouettes to their corresponding front‐view faces. This task involves sophisticated calculation in pictorial information, precise viewpoint transformation, and most probably a 3‐D face representation. The results showed that although the performances were well above chance level in the recognition of familiar faces, for children, they were at chance level in the recognition of unfamiliar faces. The results indicate that children, at least to the age of about 12 years, are still immature in the processing of face viewpoint transformation compared to adults.
